In the Belle Époque, Belgium recorded an unprecedented trade boom, but growth in output per capita was lackluster. We seek to reconcile this ostensible paradox. Because of the sharp decline in both fixed and variable trade costs, the trade boom was as much about the expansion in the number of products delivered and markets served as it was about shipping more of the same old products. We use a new highly disaggregated data set on bilateral exports at the product level to illustrate these claims. In line with new trade theory, the effect of trade on productivity was mediated by sector-level firm heterogeneity and product differentiation. In new technology sectors, like tramways, the high degree of firm heterogeneity amplified the effect of trade on productivity. But in other sectors, mainly...

Historians have long wondered whether the Southern Confederacy had a realistic chance at winning the American Civil War. We provide some quantitative evidence on this question by introducing a new methodology for estimating the probability of winning a civil war or revolution based on decisions in financial markets. Using a unique dataset of Confederate gold bonds in Amsterdam, we apply this methodology to estimate the probability of a Southern victory from the summer of 1863 until the end of the war. Our results suggest that European investors gave the Confederacy approximately a 42 percent chance of victory prior to the battle of Gettysburg/Vicksburg. News of the severity of the two rebel defeats led to a sell-off in Confederate bonds. By the end of 1863, the probability of a Southern vi...

The occupation payments made by France to Nazi Germany between 1940 and 1944 represent one of the largest recorded international transfers and contributed significantly to financing the overall German war effort. Using a neoclassical growth model that incorporates essential features of the occupied economy and the postwar stabilization, we assess the welfare costs of French policies that funded payments to Germany. Occupation payments required a 16 percent reduction of consumption for twenty years, with the draft of labor to Germany and wage and price controls adding substantially to this burden. Vichy%u2019s postwar debt overhang would have demanded large budget surpluses; but inflation, which erupted after Liberation, reduced the debt well below its steady state level and redistributed t...
